Bristol Yarn Gallery yarn?

I am looking at using Bristol’s King George for the Champagne wrap from Elann. What do y’all think? It is for my mother in Houston. She loves luxury (think, snob) but will this be too warm for a Houston winter? Since I don’t have an alpaca/cashmere anything I am clueless how warm it will be. It is quite lacey so perhaps it is ok. Also how well does this yarn knit up?
